While most heated hair mask products must be activated with a hair dryer, a specialized hair dryer cap or at the very least, a towel wrap, Redken's Heatcure At-Home Self-Heating Mask boasts packaging that does all the heating itself.
The hair care product is packaged in a small, single-use sachet, so that when the label on the front is peeled off, air enters the package. Immediately, this causes a reaction that triggers the self-heating features of the product. This process reminds of the way that pocket-sized hand warmers provide a source of heat, as they are activated with exposure to air.
The design of Redken's Heatcure At-Home Self-Heating Mask sachet was recently recognized with an award for technical innovation at the 2017 Flexible Packaging Achievement Awards.
